Getting to 4-0 isn't going to be easy – that could be the overriding theme of Week 4, the final round of September games in the NFL's 2024 schedule.
All five undefeated teams are likely to be tested, starting with the Minnesota Vikings and Pittsburgh Steelers, who will hit the road Sunday afternoon to face the Green Bay Packers and Indianapolis Colts, respectively, at 1 p.m. ET. The Vikes' divisional showdown at Lambeau Field will also feature the subplot of RB Aaron Jones' return to Wisconsin in enemy colors.
The Kansas City Chiefs might have the best odds of remaining unbeaten as they visit the battered Los Angeles Chargers during Sunday afternoon's late window.
